MAINTENANCE

WARNING

Remove test leads before changing battery or fuse

or performing any servicing.

Battery Replacement

Power is supplied by a 9 volt "transistor" battery. (NEDA 1604, IEC 6F22). The
"

" appears on the LCD display when replacement is needed. To replace the

battery, remove the two screws from the back of the meter and lift off the
battery case. Remove the battery from battery contacts.

Fuse Replacement

If no current measurements are possible, check for a blown overload protec-
tion fuse. There are two fuses; F1 for the "mA" jack and F2 for the "10A" jack.
For access to fuses, remove the four screws from the back of the meter and
lift off the battery cover and case. Replace F1 only with the original type 0.5A/
250V, fast acting ceramic fuse. Replace F2 only with the original type 10A/
600V, fast acting ceramic fuse.

Cleaning

Periodically wipe the case with a damp cloth and detergent, do not use
abrasives or solvents.
